latter as a stop to limit the projection of the bolt. The'bolt also carriesa pin 24 which extends through a slot 25 formed in thebody 140i the 'bolt actuating member, and thus the latter element is also guided, and restrained from improper movemejnts, it being borne, in mind that the forward edge of this I exerted through the extension 13 and body 1 1' Primarily-considering that the parts are in a position illustrated in Fig;

This-willob vr ously'cause a retraction of thebolt 7 to a position substantially in line with the forward L face of the casing 55. 4 e r With a viewto' shiftingv the supplemental I bolt, it will be observed that a lever 26is employed, the forward end of which terminates within the notch {29, this action will cause" preferably in a eircular bearingiface or head 27 lying within. a recess formedfin the upper that initial moven ent on the part ofthe crank 12 will cause, as' has been illustratedin Fig.

Thereafter, this bolt will be carried in retractedposition during the re-1 traction of the bolt 7 as has; been shown in Figal'and subsequently as the body 14 moves downwardly, the parts willoagain reach the A position shown'in Fig. 1.insofar as the projection of the supplemental bolt isconcerned. Aprqection of the parts will obviously be i efi'ected under a reversal of the' foregoing procedure, and thus it will be ob'viou's'that the supplemental boltwill atno time be projected until the main bolt is wholly projected and accordinglythe opening of the keeperis inline with the path of travel of the supplemental bolt; Also, and conversely,

that ifipress'ure-is brought to bear against the bolt ,7 in "an attempt-to force the same rearwardly,that aside from any cooperation V of the supplemental bolt 9.with thekeeper V such movementwill be prevented due to the engagement between the rear edge of the body '14 and thelug 31. This, ofgcourse, is supplemental to theadditionalaction preventative factor occurring due to the fact that the crank 12 and/or17 will be in aposition where it will be necessary to effect a turning thereof in order to permit ofrearwardjl movement of the extension 13' and accordingly the body'14: and associated'structure. Fi

nally, it will be observed a View to assisting'the bolt action and also to present an accidentalfmovem'ent of the parts that a spring 32 may be provided which has oneof base of aslot formed in therear edgeof the bolt 7 its body being coiled around the pin 1 From the foregoing, it that among others, the several objects as specifically aforementioned are achieved. Additionally, it will be, understood that a its ends'bearing conveniently against the' sis- 24 and itsopposite end bearing against the pin 28 carried by the lever 26. 5 v
